Ants of the Genus <Emphasis Type="Italic">Fallomyrma</Emphasis> Dlussky et Radchenko (Hymenoptera,Formicidae, Myrmicinae) from Late Eocene European Ambers

The extinct monotypic ant genus Fallomyrma was described by Dlussky and Radchenko in 2006 based on workers from Late Eocene Rovno (Ukraine), Scandinavian (Denmark), and Bitterfeld (Germany) ambers. Three new Fallomyrma species from the Rovno amber are here described based on workers: F. anodonta sp. nov., F. marginata sp. nov., and F. robusta sp. nov. A key to all known species of this genus is compiled. The quantity ratios (of the numbers of species and specimens) of Fallomyrma and other amber Myrmicinae genera are considered. The opinion of the autochthonous origin of the Rovno amber is confirmed.     

Have ladybird beetles and whiteflies co-existed for at least 40 Mya?

The beetle family Coccinellidae is rarely recorded from fossils. Most of the records come from the nineteenth and beginning of the twentieth century. A complete list of Coccinellidae records from Baltic amber is presented and discussed. Extensive literature research provided a surprising conclusion that not a single species of Coccinellidae has been formally described from Baltic amber till now. The first two species of ladybird beetles from Eocene Baltic amber are described and placed in the genus Serangium, namely S. twardowskii sp. nov. and S. gedanicum sp. nov. Their phylogenetic placement in the subfamily Microweiseinae is provided. A key to the fossil species of Serangium is given. Extant representatives of the genus are distributed mainly in tropical areas of Asia and Oceania, and are specialised predators of whiteflies. Current discovery shows that during the Middle Eocene, the genus Serangium was distributed wider in the Northern Hemisphere and the evolution of these ladybird beetles was probably influenced by the evolution of whiteflies which are also found in the Baltic amber.     

A new caddisfly of the fossil genus <Emphasis Type="Italic">Archaeotinodes</Emphasis> (Insecta: Trichoptera: Ecnomidae) from the Baltic amber

A new caddisfly species of the fossil genus Archaeotinodes, A. igneusaper sp. nov., is described from the Upper Eocene Baltic amber. The new species is close to A. pauper Ulmer, 1912 and A. lanceolata Ulmer, 1912 from the Baltic amber, differing from these in the structure of the male genitalia.     

New taxa of soft-winged flower beetles (Coleoptera,Malachiidae) in Baltic and Rovno amber

Two new genera and three new species of soft-winged flower beetles (Coleoptera, Malachiidae) are described from Rovno and Baltic Eocene amber. Protocephaloncus gen. nov. with the type species P. perkovskyi sp. nov. was found in the Rovno amber. It differs from its congeners in the tribe Troglopini in the primitive sculpture of the male facial area as a longitudinal narrow depression between the eyes lacking an appendage inside, and two trapezoid impressions on both sides of the depression closer to its lower part. A transverse pronotum, slightly rounded, but not sinuate posteriorly, is also a diagnostic feature of the new genus. A new genus of the tribe Attalini, Palpattalus gen. nov., was found in the Baltic amber. The tarsal comb on the anterior second tarsomere of the male, complicatedly curved pygidium, and cylindrical apical palpomere allow the definite attribution of the genus to the tribe Attalini. The characteristically enlarged, rounded and slightly flattened 1st palpomere, possessing a long seta directed outward, of the new genus resembles similar structures found in members of the tribe Colotini, all males of which have modified and enlarged 3rd and 4th palpomeres. Probably, Palpattalus gen. nov. represents an ancestral form for these two tribes. This allows the establishment of independent status for Antholinus Mulsant and Rey, 1867 stat. resurr., with anterior tarsi in males lacking comb on the second tarsomere, in contrast to all other subgenera of Attalus Erichson, 1840. Males of two different species, Palpattalus baltiensis sp. nov. and P. eocenicus sp. nov., were found as inclusions in Baltic amber. They differ in the coloration of the elytra, yellow with black spots in Palpattalus baltiensis sp. nov. and unicolorous black in P. eocenicus sp. nov.; the shape of pygidia, longitudinal and strongly elongated in P. baltiensis and transverse and rounded in P. eocenicus, and in a number of other characters.     

Species of two paleoendemic sap beetle genera of the Tribe Nitidulini (Nitidulidae: Coleoptera) from the Baltic and Dominican amber

Omositoidea gigantea Schaufuss, 1892 is redescribed; O. pubescens sp. nov. from the Baltic amber, Palaeometopia dominicana gen. et sp. nov. and P. colorata gen. et sp. nov. from the Dominican amber are described. The taxonomic position of the two genera and their probable bionomy are discussed.     

Two new genera of cuckoo wasps (Chrysididae: Amiseginae) from Rovno and Baltic ambers

Cuckoo wasps of the subfamily Amiseginae, Eosega heterotarsata gen. et sp. nov. and Foveorisus kilimniki gen. et sp. nov., from the Late Eocene Baltic (Russia) and Rovno ambers (Ukraine), respectively, are described. Primitive Eosega is close to the extinct genus Palaeobethylus Brues in Kieffer, 1914 and represents the so-called American series of genera of Amiseginae. Foveorisus is found to be morphologically close to a number of extant oriental genera. All known fossil Amiseginae are listed. Stick insects of the family Archipseudophasmatidae, possible hosts of the Eocene amisegines, are recorded in the Rovno amber for the first time.     

New weevils (Curculionidae) in Baltic amber

The new subtribes Palaeorhamphina subtrib. nov. of the tribe Rhamphini and Eocenesibiniina subtrib. nov. of the tribe Tychiini, new genera Archaeoeugnomus gen. nov. (type species A. balticus sp. nov.), Palaeorhamphus gen. nov. (type species P. primitivus sp. nov.), and Eocenesibinia gen. nov. (type species E. prussica sp. nov.), new subgenus Palaeoleiosoma subgen. nov. (type species L. klebsi sp. nov.) of the genus Leiosoma Stephens, and new species Leiosoma klebsi sp. nov., Caulophilus rarus sp. nov., C. squamosus sp. nov., Ceutorhynchus alekseevi sp. nov., C. electrinus sp. nov., Dorytomus nudus sp. nov., Pachytychius eocenicus sp. nov., Archaeoeugnomus balticus sp. nov., Palaeorhamphus primitivus sp. nov., Orchestes tatjanae sp. nov., and Eocenesibinia prussica sp. nov. are described. Electrotribus Hustache, 1942 placem. nov. is transferred from the tribe Derelomini of the subfamily Curculioninae to the tribe Acicnemidini of the subfamily Molytinae. Succinostyphlus erectosquamata (Rheinheimer, 2007) placem. nov. et comb. nov. is transferred from the genus Electrotribus Hustache, 1942 to the genus Succinostyphlus Ku?ka, 1996. These are the first records of representatives of the tribes Plinthini, Acicnemidini, Eugnomini, and Rhamphini in the Baltic amber.     

First gall midges (Diptera,Cecidomyioidea) from Late Cretaceous amber of the Taimyr Peninsula

Gall midges from Santonian amber of Yantardakh (Taimyr Peninsula) are investigated for the first time. Eight new genera and eight new species belonging to five tribes of the subfamily Micromyinae (Lestremiidae) are described. These are Caputmunda yantardakhica gen. et sp. nov. (Catochini), Cretoperomyia taimyrica gen. et sp. nov. (Peromyiini), Palaeostrobliella dmitrii gen. et sp. nov., Yantardakhiella pusilla gen. et sp. nov., and Zherikhiniella pedicellata gen. et sp. nov. (Strobliellini), Menssana norilsk gen. et sp. nov. (Micromyini), and Cretomycophila ekaterinae gen. et sp. nov., and Corporesana khatanga gen. et sp. nov. (Aprionini). A representative of Porricondylinae (Cecidomyiidae, Porricondylinae, Holoneurini) is recorded. The diagnoses based on morphometric parameters of tribes and previously established genera are emended. The species composition of gall midges from three Cretaceous amber faunas of different ages are analyzed.     

A new species of derelomine weevils (Coleoptera,Curculionidae, Curculioninae: Acalyptini) from the Rovno amber

Protoceletes hirtus sp. nov. (Curculionidae: Curulioninae: Acalyptini) from the Late Eocene Rovno amber is described. This is the second fossil of the genus. The new species is close to P. wolfschwenningerae Rheinheimer, 2007 from Baltic amber and differs it in the separated coxae, asymmetrically convex eyes, longer and clearly semierect hairs on the surface, and the longer body.     

A new genus of seed beetles (Coleoptera,Chrysomelidae, Bruchinae) in Baltic amber

The new genus and new species of seed beetles (Copeoptera, Chrysomelidae, Bruchinae) Electrocaryedon poinari gen. et sp. nov. are described from the Late Eocene Baltic amber. This new genus differs from the genus Caryedon Schoenherr, 1823 in the completely separate procoxal cavities, not shortened lateral carina on pronotum, and wider body with sparse setae.     

Ants of the tribe Formicini (Hymenoptera,Formicidae) from Late Eocene amber of Europe

The tribe Formicini (Formicinae) from the Late Eocene Baltic, Bitterfeld, Rovno, and Scandinavian ambers is revised. Ants are recorded for the first time from the Bitterfeld and Scandinavian ambers. Two new genera (Cataglyphoides gen. nov. and Conoformica gen. nov.) and six new species (Cataglyphoides intermedius sp. nov., Conoformica bitterfeldiana sp. nov., Formica kutscheri sp. nov., F. palaeopolonica sp. nov., F. radchenkoi sp. nov., F. zherikhini sp. nov.) are described. A new combination, Cataglyphoides constrictus (Mayr, 1868), comb. nov., is established. A lectotype of Camponotus constrictus Mayr, 1868 and a neotype of Formica phaethusa Wheeler, 1915 are designated. Formica clymene Wheeler, 1915 is recognized as a new synonym of F. phaethusa Wheeler, 1915. An identification key for workers of Formicini species from Late Eocene European ambers is provided.     

A new species of the genus <Emphasis Type="Italic">Nalassus</Emphasis> Mulsant (Coleoptera: Tenebrionidae: Helopini) from the Baltic amber

The first Eocene species of the tribe Helopini, Nalassus klebsi sp. nov., from the Baltic amber is described. The new species is included in the nominative subgenus and similar to the extant species N. dermestoides (Illiger) and N. laevioctostriatus (Goeze), from which it differs in the shape of eyes (eyes are considerably less transverse than in living Palearctic species of the genus Nalassus Mulsant), the shape of the pronotum with acute posterior angles (other Palearctic Nalassus have obtuse or straight pronotal angles) as well as convex elytral intervals. Species of the less specialized nominative subgenus are widespread in forests and (partly) alpine landscapes of Europe (eastwards up to the Urals) and eastern Asia.     

Gall midges of the supertribe stomatosematidi (Diptera,Cecidomyiidae) in the Palaearctic region,with descriptions of new taxa from the late Eocene Rovno Amber. 2. The genera <Emphasis Type="Italic">Didactylomyia</Emphasis> and <Emphasis Type="Italic">Rovnodidactylomyia</Emphasis> gen. n.

One new genus (Rovnodidactylomyia Fedotova et Perkovsky, gen. n.) and four new species (Didactylomyia dlusskyi sp. n., Rovnodidactylomyia zosimovichi gen. n. et sp. n., R. sidorenkoi sp. n., and R. iconica sp. n.) are described from an amber sample of the late Eocene Period (Rovno District, Ukraine). Two species from a Baltic amber sample of the late Eocene Period, described earlier in the genus Bryocrypta, are attributed to the genus Rovnodidactylomyia (R. girafa (Meunier, 1904) comb. n. and R. capitosa (Meunier, 1904)). The first fossil species of the genus Didactylomyia is described for the first time; two contemporary Palaearctic species are recorded. Keys to the species of the genus Didactylomyia are given.     

A new species of the genus Smicrips Le Conte (Coleoptera: Smicripidae) from Baltic amber

Smicrips gorskii sp. nov. from the Upper Eocene Baltic amber, distinguished from all congeners by the dark color and very long antennomere 2 is described.

Brachiopods from the family Ambocoeliidae George (Order Spiriferida) from the Emsian (Lower Devonian) of northeastern Russia

Brachiopods from the family Ambocoeliidae George from the Emsian (Lower Devonian) of northeastern Russia are described: Bisinocoelia despecta sp. nov.; Yakutospirifer gen. nov. with the type species Y. krivensis sp. nov.; Micospirifer gen. nov. with the type species M. simplex sp. nov.; Kolymospirifer gen. nov. with the type species K. optatus sp. nov. (subfamily Ambocoeliinae); Datnospirifer gen. nov. with the type species D. alius sp. nov.; Khalimospirifer gen. nov. with the type species Kh. microscopicus sp. nov.; Gerospirifer gen. nov. with the type species G. normalis sp. nov., and G. gerensis sp. nov.; Dogdospirifer gen. nov. with the type species D. yolkini sp. nov. (subfamily Rhynchospiriferinae).     

The first record of the subfamily Xenoscelinae (Coleoptera,Erotylidae) from the Baltic amber

The first Erotylidae of the subfamily Xenoscelinae from the Late Eocene Baltic amber, Warnis tvanksticus gen. et sp. nov., is described. The new genus is distinguished from closely related Xenoscelis Woll. and Zavaljus Reitt. by the presence of well-developed femoral lines on the first abdominal ventrite and also the shape of the pronotum, the body size, the absence of lateral carina on the elytra or pits at the base of the pronotum, and the presence of a gular pit.     

New Devonian brachiopods from northeastern Russia

Brachiopods from the Devonian of northeastern Russia are described: Eoprokopia gen. nov., with the type species E. aequalis sp. nov. (subfamily Prokopiinae, order Orthida); Davoustia settedabanica sp. nov. and D. verkhojanica sp. nov. (family Anopliidae, order Chonetida); and Alkhovikovia gen. nov. with the type species A. libera sp. nov. and A. importuna sp. nov. and Tikhyspirifer gen. nov. with the type species T. globosus sp. nov. (subfamily Rhynchospiriferinae, order Spiriferida).     

Neogene phasianids (Aves: Phasianidae) of Central Asia: 1. Genus <Emphasis Type="Italic">Tologuica</Emphasis> gen. nov.

A new genus, Tologuica, with two species (T. aurorae sp. nov. and T. karhui sp. nov.), from the Middle Miocene of the Sharga locality (western Mongolia) is described. The new genus shares some characters with the extinct genera Palaeocryptonyx, Palaeortyx, and Plioperdix and with extant Coturnix. The foot structure suggests that Tologuica resembled in ecology the European genus Palaeortyx and was probably adapted to an arboreal mode of life, in contrast to the terrestrial Coturnix and Plioperdix.
